Cdte Solar Panel Efficiency

Cigs cells also use the toxic chemical cadmium.

Cdte solar panel efficiency.

Based on first solar s proven cdte technology series 6 retains all of the performance and reliability advantages featuring premium components and globally consistent high quality manufacture. Cdte thin film solar cells can be manufactured quickly and inexpensively providing a lower cost alternative to conventional silicon based technologies. In august 2014 first solar announced a device with 21 1 conversion efficiency. Recent improvements have matched the efficiency of multicrystalline silicon while maintaining cost leadership.

The record efficiency for a laboratory cdte solar cell is 22 1 by first solar while first solar recently reported its average commercial module efficiency to be 16 1 at the end of 2015. The new paper reports a cell efficiency of 20 8 representing a crossing point for the new group v technology relative to historic copper technology. The united states is the leader in cadmium telluride cdte photovoltaic pv manufacturing and nrel has been at the forefront of research and development in this area. However cdte panels have a higher percentage of cadmium and cigs cells are a relatively responsible thin film option for the environment.

In 2014 the record module efficiency was also raised by first solar from 16 1 up to 17 0. Cdte is an ideal absorber material for high efficiency low cost thin film polycrystalline solar cells. With efficiencies exceeding 20 measured in the laboratory there may be a continuing place for high efficiency cigs panels in the general solar panel market. Another nine are from first solar the arizona company that is the market leader for the production and sale of cdte thin film solar panels.

First solar hits record 22 1 conversion efficiency for cdte solar cell 4 about a year ago first solar crushed the conversion efficiency mark for cadmium telluride with a world record 21 5. Pv solar cells based on cdte represent the largest segment of commercial thin film module production worldwide.

Cdte is a direct bandgap material with an energy gap of 1 5 ev and an absorption co efficient around 104 cm 1 in the visible region which means that a layer thickness of a few micrometers is sufficient to absorb 90 of the incident photons. Drawbacks of cadmium telluride photovoltaics.
